(1) Documents are served ex officio without the document to be served requiring certification. Service may be effected by posting the documents to the addressee under his or her address; section 184 (2) sentence 1, 2 and 4 of the Code of Civil Procedure applies accordingly. Where the service is to be made on domestic territory, the document is deemed to have been served three days after being dispatched.
(2) Service is not made to persons with unknown residence. If such persons have a representative empowered to receive any documents to be served, the documents are to be served on such representative.
(3) The insolvency court may charge the insolvency administrator with serving the documents referred to in subsection (1). The insolvency administrator may use a third party, in particular own members of staff, to serve the documents and to file them. The insolvency administrator is required to add the notices given in accordance with section 184 (2) sentence 4 of the Code of Civil Procedure to the court files without delay.
